GEO Checker

GEO Checker (geochecker.net) is an AI search visibility tool for generative engine optimization (GEO). Add your brand, the competitors you care about, and the real questions buyers ask; the GEO Checker Chrome extension sends the same prompts to ChatGPT, Gemini, Grok, Google and other AI engines from the browser sessions where you are already signed in, with no API keys or copy and paste, and captures the answers real users actually see instead of simulated estimates. It then measures your visibility score (the share of usable answers that name your product or cite your site), compares share of voice against competitors, shows the domains and pages AI cites, and tracks the trend run after run. An Opportunity report reviews the last 30 days of prompts, mentions and competitor citations and groups next steps into new content, page updates, outreach and community work. Core monitoring history stays in your browser, and the extension never edits your website. The Free plan includes ChatGPT, Gemini, Grok and Google, one brand workspace, up to 10 prompts and unlimited runs; Pro adds Claude, Perplexity, DeepSeek, Kimi and Doubao, unlimited prompts and CSV/PDF exports. Free web tools include a classic URL-based GEO checker, GEO checklist, llms.txt checker, hreflang checker and sitemap inspector.
